SUBJECT TO ELECTROSTATIC DAMAGE
OR DECREASE IN RELIABILITY.
HANDLING PRECAUTIONS REQUIRED.
After unpacking the HDSL2 unit, inspect it for damage.
If damage has occurred, file a claim with the carrier,
then contact ADTRAN Customer Service. Refer to the
Warranty and Customer Service
information. If possible, keep the original shipping
container for returning the T200 H2TU-R for repair or
for verification of shipping damage.
CAUTION
Electronic modules can be damaged by
Electro-Static Discharge (ESD). When
handling modules, wear an antistatic discharge
wrist strap to prevent damage to electronic
components. Place modules in antistatic
packing material when transporting or storing.
When working on modules, always place them
on an approved antistatic mat that is electri-
cally grounded.
There are no configuration switches for the T200
H2TU-R. Configuration is performed via software
discussed in the Control Port Operation-HDSL2
of this practice.
The T200 H2TU-R plugs directly into the enclosure. No
installation wiring is required.
Instructions for Installing the Module
To install the HDSL2, perform the following steps:
1. Hold the unit by the front panel while supporting
the bottom edge of the module and engage the
enclosure edge.
2. Align the unit edges to fit in the lower and upper
guide grooves for the enclosure slot.
3. Slide the unit into the access module slot.
Simultaneous thumb pressure at the top and at the
bottom of the unit will ensure that the module is
firmly seated against the backplane of the chassis.
When the unit first powers up it runs the a series of self-
tests. Once the power up self-test is complete the status
LEDs will reflect the true state of the hardware.
